Collab Viewer Vs Product Viewer Camera

Hi All
The camera in the ProductViewer template 4.22 was great for my purposes. You can click on a mesh, the camera’s focus changes and the camera orbits around that selected mesh. The Collab Viewer template in 4.23 supports mesh smoothing (which is great), but the camera doesn’t behave like the 4.22 viewer. It seems to orbit its own axis. How can I set up the camera to behave like the old Product Viewer in 4.22? I’m quite new to UE4 sorry. Can anyone point me in the right direction?

cheers Steve
